Main application fields
natural rubber
NR
It has good wear resistance, high elasticity, breaking strength and elongation. However, it is easy to age in air, become sticky when heated, swell and dissolve in mineral oil or gasoline, and is alkali-resistant but not strong acid-resistant.
-50~70
It is often used as a raw material for manufacturing adhesive tapes, hoses and rubber strips, and is suitable for manufacturing shock-absorbing components and products used in hydroxyl-containing liquids such as automobile brake oil and ethanol.
nitrile rubber
Nitrile-butadiene rubber (abbreviation of nitrile-butadiene rubber)
It has good oil resistance, heat resistance, wear resistance, solvent resistance and high pressure oil resistance. But it is not suitable for polar solvents, such as ketones, ozone, nitrohydrocarbons, and? And chloroform.
-40~ 120
It is often used to manufacture fuel tanks and lubricating oil tanks, as well as fluid media such as petroleum hydraulic oil, gasoline, water, silicone oil, diester lubricating oil and glycol hydraulic oil.
Hydrogenated nitrile rubber
HNBR
Compared with nitrile rubber, nitrile rubber has better wear resistance, corrosion resistance, tensile resistance, tear resistance and compression flexibility, and has good weather resistance under atmospheric conditions such as ozone and sunlight, but it is not recommended to be used in alcohols, esters or aromatic solutions.
-40~ 150
Commonly used in air conditioning and refrigeration industries, widely used in environmental protection refrigerant R 134a system seals. Automobile engine system seal.
silicon rubber
Conversation interference degree
It has good heat resistance, cold resistance, ozone resistance and atmospheric aging resistance. It has good electrical insulation performance. The tensile strength and wear resistance are worse than ordinary rubber, and there is no oil resistance.
-55~250
It is often used for seals or rubber parts used in household appliances industry, seals in food machinery industry, or seals on various articles in contact with human body.
EPDM
EPDM
Excellent weather resistance, aging resistance, ozone resistance and chemical stability, resistance to freon and various refrigerants.
-50~ 150
Seals commonly used in high temperature water vapor environment; Sanitary equipment seals or parts; And seals for refrigerators and refrigeration equipment.
viton
FKM
Good high temperature resistance, chemical resistance, resistance to most oils and solvents (except ketones and esters). Poor cold tolerance.
-20~220
Commonly used in high temperature, chemical corrosion and oil-resistant working environment, widely used in metallurgy, chemical industry, automobile, electric power and other industries.
butyl rubber
Butyl rubber (abbreviation of Isobutylene-Isoprene Rubber)
Impermeability to most common gases, good resistance to sunlight and ozone, and exposure to animals or vegetable oils or oxidizable chemicals.
-55~ 100
It is usually used to make rubber parts for chemical corrosion resistance and vacuum equipment.
chloroprene rubber
China Railway (China Railway)
It has good elasticity, wear resistance and atmospheric aging resistance, is not afraid of severe deformation, and has flame retardancy. Chemical properties are stable.
-40~ 100
Suitable for making all kinds of parts in direct contact with the atmosphere, sunlight and ozone; Suitable for all kinds of fire-resistant and chemical-resistant rubber products.
polytetrafluoroethylene
polytetrafluoroethylene
Good chemical stability, good heat, cold, oil, water, steam, chemicals and other media; High mechanical strength, high pressure resistance and good wear resistance; Low friction coefficient and good self-lubrication.
-55~260
It is used to manufacture wear rings, guide rings and retaining rings. It is a common sealing material in machinery and is widely used in metallurgy, petrochemical, engineering machinery, light industrial machinery and other fields.
polyurethane
polyurethane
High strength, excellent wear resistance, good oil resistance and solvent resistance, especially good swelling resistance and ozone resistance to lubricating oil and fuel oil. But it is not resistant to high temperature.
-45~ 1 10
Used for manufacturing reciprocating seals and seals under various wear-resistant and high-strength working conditions.
Perfluorinated rubber
FFKM
It has excellent chemical medium resistance, high temperature resistance, heat resistance, chemical resistance, excellent air tightness and plasma resistance, but it has poor low temperature resistance, high raw material price and difficult production and processing.
-25~320
Resistant to all kinds of harsh chemical media and high temperature, it is often used in cutting-edge fields such as semiconductors, medical care, military industry, aerospace and so on.
